Mapper.xml传入List返回List写法

例如：
xml

<select id="tdGyzdDescList"  parameterType="java.util.List" resultType="string">
        select ZD_GUID from td_gyzd where ZD_GUID in
        <foreach collection="list" index="index" item="item" open="(" separator="," close=")">
            #{item,jdbcType=VARCHAR}
        </foreach>
        ORDER BY CREATE_DATE DESC
    </select>

dao层

 List<Object> tdGyzdDescList(List<String> zdGuidList);
